You're either lucky or inexperienced to have never been in a professional environment by 2016 where you and/or other men had to grit their teeth because they couldn't criticise a woman's ideas because of your gender (and her's). We all know the tactic of emasculation you're using: "are you not man enough to handle competitor from women?!" As you can see by the other comments in this thread, you can see most men have learned to ignore the ad hominem in these cases and focused on rational cause-and-effect approaches.
